r Patented May 25.,y 1,926.
UNITED STATES PATENT* OFFICE.
FREDERICK CHARLES LANGE AND PAUL WILLIAM LANGE, OF CASPER, WYOMING.
ANTIRATTLER FOR AUTOMOBILE CAM SHAFTS.
Application filed February 18, 1924. Serial No. 693,724.
One object of our said invention is the provision of simple, easily applied and efficient means for preventing in an automobile rattling due to endwise play of the cam shaft on which is carried a timing gear and the rotary portion of a commutator. n
Another object of our invention is to eliminate some of the wear off of the timer roller, and commutator case; and further tocreate a better contact between timer roller and commutator, thereby creating better ignition. Another feature is its simplicity of construction and its easy installation on the shaft for which it is intended as there Yare noholes to bore or machinery of any kind in order to install.
To the attainment of the foregoing, the invention consists in the improvement as hereinafter described and definitely claimed.
In the accompanying drawings, forming part of this specification Figure lis a sectional view showing our improvement as applied.v v
Figure 2 is an enlarged diametrical sec- Vtion showing in detail the application of our improvement to the end of the cam shaft.
Figure 3 is a view showing in side elevation the casing and plunger of our impr0vement.
Similar numerals of reference designate corresponding parts in all of the views of the drawings.
In Figure 1 the cam shaft 1 is illustrated as arranged in a bearing 2 in an engine casing 3 and as equipped with a timing gear 4 and with a rotary. commutator portion 5 all of which are of the ordinary well known construction, though they may be of any other appropriate construction without in# volving departure from the scope of our claimed invention. v y
The commutator illustrated also includes a casing 6 adjustable `about its aXis in the usual manner and `provided at 7 with an indenture to receive a teat 8 on the usual bracket arm 9 supported as shown on a part 10 of the engine.
The end of the cam shaft 1 is threaded as shown and is ordinarily equipped with a nut that is opposed to an ordinary sleeve 11. I
In accordance with our invention the nut alluded to is removed from the cam shaft l and its place is taken by an interiorly threaded casing 12, Figures 1 to 3 provided 55 in its end wall with a smooth bore aperture yendvvise t0 the projection 7 on the casing 6.
In consequence of this relative arrangement the said spring-pressed plunger will serve efficiently to prevent rattling or any otherv noise incident to any endwise play of the shaft 1 that may take place. v
It will be apparent from the foregoing that notwithstanding its efficiency for the purpose indicated ourk improvement is adapted to be quickly and easily applied without the employment of skilled labor and without the assistance of any tool other than an ordinary nut wrench.
We have entered into a detailed description of the construct-ion and relative arrangement of the parts embraced in the present and preferred embodiment of our invention in order to impart ya full, clear and exact understanding of the said embodiment. We do not desire, however, to'85 be understood as coniningourselves to the' specific construction and relative arrangements of parts inasmuch as in the future practice of the invention various changes andmodifications may be made such as fall within the scope of our invention as defined in our appended claim. f
Having described our invention, what we claim and desire to secure by Letters- Patent, is
The combination in an automobile engine, of a shaft, a casing receiving a portion of the said shaft and having an interior protuberance, a casing threadedly secured on the end portion of the shaft and having an inwardly directed flange at its end remote from the shaft end, and aspring-pressed plunger carried in the latter casing and the spring being housed in said plunger and movable therein and opposed to the pro- .interposed between the end of the shaft and tuberance of the lirst-nanied casing to prethe end of the plunger. 10 vent rattling or endwse play of the shaft In testimony whereof we afx our signaand having a flange opposed to the rsttures.
named flange; the plunger being hollow and FREDERICK CHARLES LANGE. movable rectilinearly in said aperture, and PAUL WILLIAM LANGE.
